I’ve made fun of the Poland curse, but I’m no exception when it comes to comedies. The general rule has always been that if I really like something that I consider to be funny (Election, Rushmore, Greenberg, Hot Tub Time Machine), it’s going to be some kind of commercial shortfall with Joe Popcorn. So it’s moderately comforting, at least, to see that Cedar Rapids, which I admire except for the third-act conclusion, has an 80% Rotten Tomatoes rating. It opens limited this weekend.
